Abstract: A system includes a heat pump including a system for conveying a refrigerant fluid between two heat exchangers, the refrigerant fluid circulating through a closed circuit; at least two heat exchangers, at least one of the first and second heat exchangers including a plurality of energy storage devices collecting a portion of the energy of the refrigerant fluid or of a secondary fluid; a system for conveying the refrigerant fluid intended to receive or transmit a given amount of energy through the plurality of energy storage devices, and a system for conveying a secondary fluid intended to receive or transmit a given amount of energy through the plurality of energy storage devices.

Abstract: A photodetection system that analyzes a luminous flux (15) received on a line (10). The photodetection system includes an opaque mask (4) provided with at least one aperture (6), placed in the vicinity of the line, driver (7) designed to rotate the mask, detector (8, 9) of an angular position of reference of the mask, a field lens (12) concentrating the luminous flux (16) crossing the line onto a photodetector (1), and a processing unit (3) connected to the photodetector, for analyzing the luminous flux to yield values for several points on the line.
